Ernest Miller Ridge - Bacon Rind Drainage

We skinned into the Ernest Miller Ridge area this morning around 8:40am. There was 18-24 inches of fresh storm snow in the bacon rind creek area. As we skinned in, we observed whoomphing and cracking throughout the basin. We ascended right of the normal trail in mellower terrain to the lower bench area. We took a break there and after discussion of the terrain and safe areas to ascend were getting ready to head to the far lookers left trees. A giant collapse happened as we were standing there and sent an almost shockwave like effect up the hill, small ripples and cracks formed way above and away from us and the entire face of Ernest Miller Ridge ripped out and ran the distance of the ridge. We were out of the way of any runout zone and away from the face so in a safe space. It was the largest remote trigger that I have ever experienced and witnessed out in the field. We took some pictures and observed the scope of the avalanche and then decided to ski some 20 degree powder slopes and head for the hills.
